So if my compression is 125, does that mean the top end might still be alright? The reason I thought it was the topend is because when I get on the throttle is bogs down, like its getting too much gas. It also puts out a little more smoke then my buddies 2 strokes do. Could this be a carb problem? I took my bike to a shop a month ago, and they played with the carb, and replaced the o ring gasket, but when I start the bike I see smoke coming out of the cyl. So im thinkiking they didnt replace the ring, or didnt do a good job.

They might have replaced it with a regular o-ring or something stupid like that. Or as you say, not replaced the ring at all. That'd account for the bogging as well I reckon. Had the same problem on my 125 when I fitted a new spannie with a few unnoticed holes... Bloody thing would bog and wouldn't pull top revs either.

I've learned a few lessons with these pipe mounts since I was going through them like candy also.  Those things ain't cheap either!!! It's extreamly important you have a straight pipe to begin with.  If there is just a slight twist in the rubber when you put those things on, they will rip in no time.  I actually will shim out the rubber mount on the bottom mount so that it mates up perfectly to pipe with no force and I've found my mounts hold up longer than they used to.  :wink:
